Why Voltra air?
Voltra gives you a complete picture of your health, tells you how to improve it, and never charges you a penny per month to access your own data.
Optimise your sleep
Not all sleep is equal. Voltra measures every stage - light, deep, REM and wake - and shows you exactly what's happening during the hours you're unconscious. Understand what's affecting your recovery, fix what's holding you back and wake up feeling the difference.

Assess your recovery
Voltra analyses how your body responds to your workouts, sleep quality, stress and menstrual cycle - so you finally understand what's actually affecting your recovery, and can adapt your effort before fatigue sets in.

Analyse your resilience
Voltra's 24/7 HRV monitoring shows how your body responds to stress and recovery, helping you decide when to push, when to pause, and spot burnout before it hits.
Member Spotlight

— Michael O.
Daily blood insights
Your blood data tells a story about your body that most people never get to read. Voltra brings that data to your wrist - tracking how your blood oxygen influences your physical, mental and emotional wellbeing every single day. No clinic required. No subscription. Just your health data, yours to keep.
Member Spotlight
"I never thought to check my blood oxygen until Voltra flagged it was dropping during the night. Within a week of making changes to my sleep position I was waking up with more energy than I'd had in years."
— James R.
Understand your unique cycle
Voltra tracks your menstrual cycle alongside your health data, helping you anticipate changes in energy, mood and performance before they happen. Understand your natural rhythm and adapt your training, recovery and daily routine around it - not against it.
Member Spotlight
“Voltra helped me understand what real rest feels like throughout my cycle.

— Jenifer D.

Really. No monthly fee, no annual renewal, no premium tier you need to unlock to see your own data. You pay once for Voltra and every single feature is yours forever from day one. No small print. No surprises.
-
Voltra Air uses the same optical sensor technology found in premium wearables. Our blood pressure readings have been independently compared against cuff readings with consistently closer than other wearables on the market.
As with any wrist-worn tracker, accuracy is best achieved by wearing the band snugly and consistently - particularly overnight for sleep and HRV data. -
Up to 40 days on a single charge. You won't be taking Voltra off to charge it every night like a smartwatch - most users charge it once every few weeks and forget about it in between.
-
WHOOP charges up to £239 a year in subscription fees on top of the device cost. Voltra Air costs £39.99. Once. That's it. Over three years, switching to Voltra saves you the equivalent of nearly £700 in subscription fees - for the same quality health data with no ongoing commitment.
